Summary:

In this work possibility of use of a monocrystal diamond(CVD and HPHT) as highly effective secondary emitter is shown.The maximum SE coefficient about 14 at working accelerating voltage is received (several times exceeds SE coefficient of used materials, such as silicon), lack of dependence on diamond type is shown, dependence on current of primary beam is revealed. Taking into account unique characteristics of diamond there is a possibility of creation of highly effective and unique detectors and converters on the basis of effect of SE.
